how Avogadro’s constant links relative atomic mass to the actual atomic mass
In: Chemistry
It’s part of how Avogadro’s number is defined.
A single atom of Carbon-12 has 1.9926469e-23 grams.
A mole containing Avogadro’s number of Carbon-12 atoms has a mass of 12.0 grams.
It just makes the amounts more reasonable to deal with mole amounts of things instead of carrying out this huge number of atoms.
